A massive black hole revolves so fast that it tests the limits of Einstein's theory of relativity and can turn the space around itself, according to a joint study by the Indian AstroSat and the Chandra X-Ray Observatory of NASA.

The black hole in question is about ten times the mass of the Sun and one of only five with a precisely measured spin speed that is so close to the speed of light.

India's first astronomy satellite, Astrosat, which was launched in 2015, was watching the fast pace of the black hole. The results were later confirmed by NASA's Chandra X-Ray Observatory.

Scientists measure black holes by their mass or spin rate, which is on a scale of 0 to 1. This black hole in the binary star system 4U 1630-47 was clocked at a phenomenal rate of 0.9 – in others very close to the limit set by Einstein's Theory of Relativity.

The incredible emptiness could also be the key to understanding the formation of galaxies.

Gas, dust and other masses from the star of the 4U 1630-47 system are torn off to form a disk around the black hole, reach temperatures in excess of 10 million degrees Celsius, and emit X-rays, which are monitored and measured by the Chandra Observatory. The overall system generates more than 10,000 times the power delivered by our sun.
